Abstract

The utility model provides a bottle blowing machine manipulator that opens and shuts, includes around rotatory supporting disk and the cam disc of axis, is equipped with the flexible cam and the cam that opens and shuts on the cam disc, is equipped with the slider of taking portable slide rail on the supporting disk, and the slide rail stretches to a bottle embryo through flexible guide pulley with the effect of flexible cam, and simultaneously, the arm that opens and shuts on the slide rail end -to -end connection board drives first tong through the guide pulley that opens and shuts with the effect of the cam that opens and shuts and opens, drives each other and opens simultaneously through gear plate again between first tong and the second tong. This bottle blowing machine manipulator that opens and shuts has realized the initiative of tong and has opened to avoid the tradition passively in the mode of opening tong twin vase embryo the injury and to the required precision of tong, and then has protected a bottle embryo effectively, and has improved the quality and the qualification rate of product, reduced the processing requirement of tong simultaneously.

Description

A kind of bottle blowing machine retractable mechanical system design hand

Technical field

The utility model is related to bottle blowing equipment, is used to capture the folding of bottle embryo or bottle in more particularly to a kind of bottle blowing machine Manipulator.

Background technology

Bottle blowing machine is the equipment that the plastic bottles such as beverage bottle, oil bottle, medicine bottle fabricate field, including is gripped and transport bottle Embryo, blown bottle embryo are multiple parts such as bottle, wherein, gripping the structure of bottle embryo as shown in Figure 1, 2, sliding block 101 is by driving Part is driven to just to bottle embryo position, then slide rail 102 is pushed away and stretches to a bottle embryo, until two tongs 103 press to bottle embryo and by bottle Embryo distending, then slide rail be no longer influenced by promote, two tongs on the one hand clamp extension spring 104 in the presence of just bottle embryo clamp, separately On the one hand bounced back in the presence of reset tension spring 105, this rear slider continues to move and by bottle germ band to next station.

Although this kind of bottle blowing machine retractable mechanical system design hand can complete bottle embryo go send work, two tongs are in clamping bottle embryo process In opening operation be the restoring force for relying on pressure between tong and bottle embryo, and extension spring, be finally pressed into and distending by bottle embryo, It is a kind of passive unfolding mode.This structure causes the processing request of tong very high to ensure to grip precision, makes difficult； Meanwhile, during bottle embryo press-in tong, it is easy to scratched by tong, can both produce chip, a bottle embryo processing essence is have impact on again Degree, even results in bottle embryo deformation and produces waste product.

The content of the invention

The utility model aims to provide a kind of tong and actively opens to grip the bottle blowing machine retractable mechanical system design hand of bottle embryo, to protect Bottle embryo, improve product quality and qualification rate, while reducing the processing request of tong.

Bottle blowing machine retractable mechanical system design hand described in the utility model, including the support plate that rotates about the axis and cam disc, support Several sliding blocks for rotating with it circumferentially are installed on disk, moveable slide rail is installed on sliding block, the end of slide rail passes through Connecting plate is equipped with the first tong and the second tong；Two tongs are articulated with connecting plate by rotary shaft, are equipped between two tongs Make its opposite extension spring for rotating, be installed with two rotary shafts with the gear teeth and pitch wheel plate, on the first tong It is also fixed that cursor is housed；Cam disc is provided with flexible cam and folding cam, is equipped with along stretching that flexible cam is moved on slide rail Contracting guide wheel, folding swing arm is equipped with connecting plate by rotating shaft, is equipped with folding swing arm and is led along the first folding that folding cam is moved Wheel and the second folding guide wheel, the second folding guide wheel can press to cursor and drive the first tong to open.

Bottle blowing machine retractable mechanical system design hand described in the utility model, sliding block is driven by support plate and moves to the position just to bottle embryo Put, then slide rail stretches to a bottle embryo by the interaction of the cam that stretched on stretch guide wheel and cam disc, meanwhile, it is installed on slide rail The folding swing arm of end is rotated by the first folding guide wheel and the interaction of folding cam on cam disc, then, folding pendulum Arm drives the second folding guide wheel to press to the cursor on the first tong, until drive the first tong to open by cursor, now, The rotary shaft being connected with the first tong is rotated, and drives another rotary shaft and the rotation of the second tong to open by gear plate, thus The work of opening of tong is realized, tong to be opened is placed on outside bottle embryo, it is right that the second folding guide wheel stops in the effect of folding cam First tong applying is acted on, and two tongs are the clamping bottle embryo under the restoring force of extension spring, completes gripping work.The bottle blowing machine opening-closing machine Tool hand by being respectively provided with folding cam and the first folding guide wheel on cam disc and guide rail, then by the second folding guide wheel to Gear plate effect between the effect of one tong and two tongs, you can opened with the active for realizing tong, so as to avoid traditional quilt It is dynamic to open injury of the tong to bottle embryo and the required precision to tong in mode, and then a bottle embryo is effectively protected, and improve The quality and qualification rate of product, while reducing the processing request of tong；The simple structure, it is easy to accomplish, and its work it is quick, Accurate and stabilization, is more favorable to the raising of product quality.

Specific embodiment

As Figure 1-3, a kind of bottle blowing machine retractable mechanical system design hand, including the support plate 1 that rotates about the axis and cam disc 2, branch Several sliding blocks 3 for rotating with it circumferentially are installed on support plate, moveable slide rail 4, the end of slide rail are installed on sliding block First tong 6 and the second tong 7 are equipped with by connecting plate 5；Two tongs are articulated with connecting plate by rotary shaft 8, two tongs Between equipped with its opposite extension spring 9 for rotating is made, be installed with two rotary shafts with the gear teeth and pitch wheel plate 10, It is also fixed on first tong that cursor 11 is housed；Cam disc is provided with flexible cam 21 and folding cam 22, and edge is housed on slide rail The flexible guide wheel 12 of flexible cam motion, folding swing arm 13 is equipped with connecting plate by rotating shaft, is equipped with along folding in folding swing arm The first folding guide wheel 14 and the second folding guide wheel 15 of cam motion, the second folding guide wheel can press to cursor and drive the first folder Hand opens.

Described bottle blowing machine retractable mechanical system design hand, cam disc 2 is provided with oscillating cam 23, fixation is installed with support plate Disk 16, sliding block 3 is rotatably installed on fixed disk by adjusting axle 17, and swing arm 18, swing arm are installed with sliding block 3 It is upper that the swing guide wheel 19 moved along oscillating cam is housed.Support plate drives slide block movement to the position just to bottle embryo, during being somebody's turn to do Realize being accurately positioned by oscillating cam and swing guide wheel, tong is just just gripped to bottle embryo, after the completion of waiting to grip, oscillating cam Can also pass through to swing guide wheel depending on the condition of production carries out angle adjustment to tong, in order to the carrying out of follow-up bottle blowing work.
